After she qualified as a doctor, Dorothy's first job was as a dispensary doctor in
Kilbrittain in County Cork, where she also engaged in the
Irish War of Independence, tending to injured members of the
Irish Republican Army. During the ensuing
Irish Civil War, she favoured the Republican side. Dorothy joined
Cumann na mBan, an auxiliary of the
Irish Volunteers, and gave lectures on
first aid as part of her involvement. Her biggest career achievements were through her involvements with
tuberculosis. She was first exposed to the disease when John Richard Green, husband of her aunt, Alice Stopford Green, died from the condition. She also attended a Tuberculosis Day in Walworth at the invitation of Mrs Anstruther, a social worker friend of her aunt. In 1923, she returned to Dublin and began work in
Saint Ultan's Children's Hospital, Dublin as a visiting physician. This was an honorary, unpaid position. Dorothy began to research and write about tuberculosis, particularly in the context of children. After a 1931 visit to
Vienna, she began to use the tuberculin test to diagnose tuberculosis. She was interested in the controversial BCG vaccine which could protect against tuberculosis. Her work with tuberculin had shown that many Irish adolescents from rural areas were tuberculin negative and vulnerable to contracting tuberculosis. She was anxious that Irish emigrants, including young Irish nurses and nurse trainees, be vaccinated. In 1949, Price was appointed as the first chairperson of the Irish National BCG Committee. She learned
German while working at St Ultan's to translate and read German literature on TB. She took a post-graduate course in Scheidess before preparing a thesis on
The Diagnosis of Primary Tuberculosis in Children, which described modern continental theories and practices, and won her an MD. She began writing her book
Tuberculosis in Childhood in 1937 and had 1000 copies of it produced by a Bristol-based publisher in 1939. She became a member for the
Red Cross Anti-TB committee, but later resigned for political reasons. In 1949 she involved
Dora Metcalfe, the Irish computing pioneer, with the vaccination programme. She was recognised for her work when Health Minister Noel Browne appointed her as Chairperson of a Consultative Council on TB. They eventually managed to open a BCG vaccination unit in St Ultan's Hospital. Her research and publications, her work on voluntary national committees and her continuous highlighting of the problem of tuberculosis in Ireland as well as her efforts to introduce tuberculin testing and BCG vaccination were pivotal in the ending of the Irish tuberculosis epidemic in the mid-20th century. ==Personal life==
